Answer:
yes
Step-by-step explanation:
Answer:
The two expression to represent area is (5 x - 10) sq. units or 5( x- 2) sq. units
Step-by-step explanation:
Here, the length of the rectangle = (x-2) units
The width of the rectangle = 5 units
Now, AREA OF A RECTANGLE = LENGTH x WIDTH
So, here AREA = 5 ( x- 2)
= (5 x - 10) sq. units
( as by Distributive property: A (B-C) = AB - AC)
Hence, the two expression to represent area is (5 x - 10) sq. units or 5( x- 2) sq. units
Answer:14315
Step-by-step explanation:
Answer:
we have
C = 1.5d
or
d=C/1.5
Step-by-step explanation:
when d is 12
C=1.5×12=18
when c=15
d=15/1.5=10
Answer:
FAIL TO REJECT
NOT ENOUGH
Step-by-step explanation:
Given a Pvalue of 0.32
Decision region :
When Pvalue < α ; Reject the Null and conclude that there is significant or enough evidence to accept the alternative hypothesis.
Otherwise, fail to reject reject the null and conclude that, there is not enough evidence to accept the alternative hypothesis
Therefore, for the scenario above, where Pvalue = 0.32
Possible α values are ; 0.1, 0.05, 0.01
For all α - values listed, the Pvalue is greater than α
Pvalue > α ; Hence, FAIL TO REJECT the Null.
Conclusion :
There is NOT ENOUGH evidence to support the alternative that the proportion of students who have ear infection at one school and the other is different.
